I can’t say enough grea I took delivery of my 2021 C8 Corvette on Friday, April 9. The C8 was ordered in early October. It has been a long process. I can’t say enough great stuff about Kwame Odum. He has been supportive, responsive and helpful throughout the 7 month-long journey. I have bought many cars over my lifetime. This is the first time for ordering a super high demand vehicle. Kwame Odum has effectively been a part of my life since late September. He has always provided sound advice in a timely manner. Truth be told, I am not a passive participant in the C8 purchasing process. But, Kwame has supported me by sharing information regarding the production status and tentative production weeks. It helped me to stay abreast of progress over this period. As previously stated, this is the first experience ordering a car. I could not imagine going through this with anyone else. Most sales relationships are completed in a few hours. Over the months I’ve worked with Kwame I’ve developed respect and appreciation for his friendly, easy going style. I have lucked out in this purchase. I want to also thank General Manager Doug Martin. Doug kept everything on track, properly documented and was always available to research questions that did not have easy answers. I have friends who have ordered C8 Corvettes from other dealerships in the northeast. None of them has had the quality of my experience with Kwame, Doug and Criswell Chevrolet of Thurmont. Thank you. It has been a privilege to work with you. More

I handed over recalls, he told me he would order parts for the recalls and then I explained my AC problem. He assured me he could find and fix the problem. He called the next day with a report and the next day it was fixed. Efficient, Friendly, Knowledgeable. John Bierman, 5 STARS!!!!!! More
